The hype is still building for the fifith iteration in the Call Of Duty series, World At War, but Activision’s CEO Bobby Kotick has already confirmed that a sixth game is being lined up for 2009.

In an earnings call with investors, Kotick also said that the title would follow the series’ “leapfrog studio strategy” – indicating that development responsibilities would switch back from WoW creator Treyarch to COD4 dev Infinity Ward.
